Turning on Modbus TCP/IP

Modbus TCP/IP

THOR comes with MODBUS TCP/IP native to the operating system and ships with Ethernet communications on board. The default status of the onboard MODBUS server is Inactive and must be turned on to operate. 

Operator will require a knowledge of MODBUS programming to configure the customer's onsite MODBUS network to accept MODBUS TCP/IP communication from THOR. ERP does not provide MODBUS integration support. 

MODBUS communication is one direction - outbound from the controller. MODBUS TCP/IP cannot be used to program the controller.

Attached to this article is the THOR MODBUS programming supplement.

To activate the MODBUS server on THOR please follow the steps outline here:
1. Navigate to the TOOLS page of the target controller



2. Open the LAN  EDIT field to configure the subnet - subnet information is provided by onsite personnel 
a. click on the three ACTION BUTTONS just to right of the LAN 
b. an Edit button will appear - Click on this Edit button



3. Configure the subnet
a. slide the DHCP Toggle from green to dark
b. Enter IP Address, Netmask, and Gateway then select UPDATE


4. Turn on the MODBUS server by sliding the Modbus TCP/IP toggle to green. 


MODBUS TCP/IP is now operational
